DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a showcase shelving device having a movable shelf that can be pulled out and installed in a showcase cabinet.

[0002]

2. Description of the Related Art Conventionally, a showcase of this type has a plurality of shelves for exhibiting products in a storage space. These shelves are movable in the vertical direction by engaging and disengaging the brackets and the engaging holes of the shelf posts, but are generally fixed in the front-rear direction. However, since it is particularly difficult to display products at the back of the shelf, conventionally, for example,
As disclosed in Japanese Patent Application Laid-Open No. 82865 (A47F3 / 06), a shelf device is constituted by movable shelves that can be pulled out in the front-rear direction, so that a clerk can pull out the movable shelves when storing products in the back of the shelves. Was.

[0003]

However, when the movable shelf is pulled out or returned, a relatively large acting force is applied to the bracket. Here, since a small gap is formed between the bracket and the engaging hole of the column because the bracket needs to be detachable, the bracket is moved by the acting force at this time, and comes off from the engaging hole. There is a risk. In particular, when a product is placed on the movable shelf in a state where the movable shelf is pulled out, a large moment is applied to the bracket, so that such a danger increases.

Accordingly, Japanese Patent Application No. Hei.
As shown in Japanese Patent No. 305493, a method of preventing a bracket from falling off by providing a fixing tool inserted into the engaging hole on the upper part of the bracket and fixed to the bracket can be considered. , The area of the movable shelf cannot be expanded to the left or right. Also,
Since the engagement hole above the bracket is used by the fixture, the bracket on the upper stage cannot be moved downward by that amount, and there is a problem that the upper and lower shelf intervals are restricted.

[0005] Further, since the rear end of the bracket is only engaged with the engagement hole, there is a danger that the leading end shifts left and right with respect to the shelf support when the movable shelf is pulled out, so-called a loss of balance. large. If the mutual brackets are shifted left and right in this way, the direction in which the rail extends and the direction of the side surface of the movable shelf will not be parallel, and the rail will be deformed and destroyed when the movable shelf is pulled out, and the shelf will drop. There was also a problem.

Therefore, it is conceivable that the brackets are connected to each other by connecting members parallel to each other in the front and rear direction. However, unless the connecting members are firmly fixed to the bracket by a plurality of screws, the brackets form mutually parallelograms. In this way, the balance of the bracket is lost. The present invention has been made to solve such a conventional technical problem, and a showcase in which operability and safety of movable shelves are ensured, and dimensions of movable shelves and restrictions on erection are eliminated. It is intended to provide a shelf device.

Another object of the present invention is to provide a shelf device for a showcase which prevents damage to a rail that allows a movable shelf to be drawn out.

[0008]

According to a first aspect of the present invention, there is provided a shelf device for a showcase, wherein a plurality of engaging holes formed in a vertical direction in a column (shelf column) provided in a refrigerator.
And a movable shelf 3 which can be freely pulled out, and a bracket 28 having a rail (slide rail) 29 for receiving the movable shelf 3
And a plurality of claws 2 formed at the rear end of the bracket 28 with a vertical interval and removably engaged with the engagement holes 24.

According to the shelf device 1 of the showcase 2 of the present invention, the engagement holes 24 between the engagement holes 24 of the shelf support 25 with which the plurality of claws 27, 27, 15 of the bracket 28 are engaged. Solid
It is fixed to the bracket 28 with the fixture 40 inserted.
As a result, even if an acting force during the movement of the movable shelf 3 is applied to the bracket 28, the bracket 40 is prevented from dropping by the fixture 40, and the fixture 40 is located between the claws 27 and 15. Therefore, it does not protrude up and down from the bracket 28 and does not hinder the mounting of the movable shelf 3 and other brackets 28.

According to the shelf device 1 of the showcase 2 of the second aspect of the present invention, for example, when a force for shifting the front part of one bracket 28 outward is applied, this force pulls the front part of one connecting member 30. . At this time, since one connecting member 30 and the other connecting member 31 are connected at the intersection, the other connecting member 31 is also pulled toward one bracket 28 at the intersection. Since the other connecting member 31 is attached to the rear part of the one bracket 28 and the front part of the other bracket 28, only the front part of the one bracket 28 cannot be moved by this force. The balance of the brackets 28, 28 is ensured.

It is screwed to. Further, the two connecting members 30 and 31 are connected to each other by a rivet 33 at the intersection.

The front surfaces of the upper surfaces of the bottom surfaces of the bracket inner plates 28A, 28A of the pair of brackets 28, 28 are
An engagement plate 32 made of stainless steel is screwed. On the front side of the engagement plate 32, an inclined surface 3 that is highly inclined rearward.
2A is formed, and an engaging portion 32B is formed continuously on the rear side of the inclined surface 32A. On the other hand, the movable shelf 3 is formed of a steel plate having a flange 34 for preventing a product from falling around the periphery thereof.
5, 35 are fixed by welding. This front reinforcement 3
As shown in FIG. 6, stoppers 36, 36 formed of strip-shaped elastic stainless steel plates are fixed to both ends of 5, respectively. The front end of the stopper 36 is the reinforcing bracket 3.
5, a rearwardly extending locking portion 36A is formed at the end of the locking portion 36A, and a guide portion 36B is formed on the rear side of the locking portion 36A. Have been. Further, a button portion 36C is formed on the front side of the locking portion 36A by protruding downward to protrude downward.
The locking portion 36A of the stopper 36 is engaged with the engaging portion 32B of the engaging plate 32 in a state where the movable shelf 3 is stored at a predetermined position in the storage room 8, thereby moving the movable shelf 3 to the bracket 28. In the disengaged state, the slide rail 29 allows the bracket 28 to slide back and forth within a predetermined range. In addition, since the engagement plate 32 is attached to the bracket inner surface plate 28A of the bracket 28, the vertical dimension of the reinforcing bracket 35 can be enlarged as compared with the related art, and the strength of the reinforcing bracket 35 itself can be improved. Thus, the connecting members 30 and 31 also need to be ordinary flat steel plates.

An inwardly protruding stopper plate 38 is fixedly welded to a lower portion of the inner surface of each of the pair of brackets 28, 28, and a screw hole 39 is formed in the stopper plate 38. As shown by the arrow in FIG.
0 are respectively fixed by screws 41. Fixture 40
Has a through hole 42 through which a screw 41 passes on the front surface, and an insertion piece 43 extending rearward from an upper portion on one side which is on the outside. When attaching the bracket 28 and the fixture 40, first, as shown in FIGS. 1 and 5, the claws 27, 27, and 15 of the bracket 28 are engaged with the engaging holes 24, 24, 24 of any height of the shelf support 25.
24 and engaged. In this case, the claws 27, 27, 1
5 is shorter than the vertical dimension of the engaging hole 24, a gap is formed between the claws 27, 27, 15 and the engaging hole 24 as shown in FIG. On the other hand, the insertion piece 43 of the fixing tool 40 has a slightly smaller vertical dimension than the engagement hole 24 of the shelf support 25, and the engagement hole 24 immediately above the engagement hole 24 with which the claw 15 of the bracket 28 is engaged. That is, as shown in FIG. 5, it is inserted from the front into the engaging hole 24 between the engaging hole 24 with which the claws 27, 27 are engaged and the engaging hole 24 with which the claw 15 is engaged, as shown in FIG. , The through hole 42 is matched with the screw hole 39 of the stopper plate 38, and the fixing tool 40 is fixed by the screw 41 to the stopper plate 3 of the bracket 28.
8 (the state of FIGS. 1 and 4). At this time, a cutout 28B is formed at the rear edge of the bracket 28 in front of the engagement hole 24 with which the insertion piece 43 is engaged, so that the insertion piece 43 can be easily inserted from the front.

The operation of the shelf device 1 with the above configuration will be described.
Locking portion 36A of stopper 36 of movable shelf 3 as shown in FIG.
However, when the movable shelf 3 is engaged with the engagement plate 32 of the bracket 28 behind the engagement portion 32 </ b> B, the movable shelf 3 is immovably supported at a predetermined position in the storage room 8 of the showcase 2. Therefore, even if the customer selects or takes out the products on the movable shelf 3, the movable shelf 3 does not move forward carelessly.

Next, when the store clerk displays the goods on the movable shelf 3, when the button portion 36C is pushed upward from the lower side in the state of FIG. 1, the stopper 36 is deformed upward by its elasticity, The locking portion 36A comes off the engagement portion 32B. As a result, the movable shelf 3 can be freely slid in the front-rear direction, so that the clerk pulls the movable shelf 3 forward as shown by a broken line in FIG.

When the movable shelf 3 is moved, the bracket 2
The action force in the front-rear direction is applied to the claws 27, 27, 15 of No. 8,
When the movable shelf 3 is fully extended, the load on the front side of the shelf device 1 becomes heavy, so the claws 27, 27,
A force is applied to move 15 upward. However, since the fixing tool 40 is attached to the stopper plate 38 at the rear end of the bracket 28, and the insertion piece 43 of the fixing tool 40 is inserted into the engagement hole 24 so as not to move up and down, the bracket 28 cannot be moved. Therefore, even if the acting force is applied to the bracket 28, the claws 27, 27,
The bracket 15 does not fall off the engagement holes 24, 24, 24 of the shelf support 25. In particular, fixture 4
0 is located between the upper claws 27, 27 and the lower claws 15, and therefore does not protrude above and below the bracket 28. Even when the bracket 28 is mounted directly above the bracket 28, there is no inconvenience such that the fixing tool 40 hinders the claw 15 of the upper bracket 28 from engaging with the engagement hole 24. In addition, since the fixture 40 comes under the movable shelf 3, it is less noticeable in appearance, and the design effect is also improved.

Next, when returning the movable shelf 3 from the drawn-out state as shown by the broken line in FIG. 2 to the original state, the movable shelf 3 is pushed into the storage room 8 as it is, and the guide portion of the stopper 36 is soon formed. 36B comes into contact with the inclined surface 32A of the engagement plate 32. Since the guide portion 36B is inclined in the same direction as the inclined surface 32A, if the movable shelf 3 is further pushed in, the stopper 3
Due to the elasticity of 6, the guide portion 36B rises along the inclined surface 32A, and eventually falls when the locking portion 36A reaches the engaging portion 32B, and the locking portion 36A engages with the engaging portion 32B. Therefore, the movable shelf 3 is stored at a predetermined position. in this way,
When returning the movable shelf 3 that has been pulled out to the original state, it is sufficient to simply push the movable shelf 3 in the direction of the storage room 8.

Here, assuming that, for example, only the front portion of the left bracket 28 is moved outward, that is, to the left when the movable shelf 3 is pulled out, this force pulls the front portion of the connecting member 30. It takes the form. At this time, since the connecting member 30 and the other connecting member 31 are connected by the rivet 33 at the intersection, the other connecting member 31 is also pulled toward the left bracket 28 toward the intersection. However, both ends of the connecting member 31 are opposite to the bracket 2 on the left side.
8 is attached to the front of the bracket 28 on the rear and right side as viewed, so that this force is applied to both brackets 28, 2
8 is a force to move to the left as a whole, and as a result, the positional relationship between the two brackets 28, 28 does not change, and the initial balance is secured.

If the balance between the brackets 28, 28 is lost, the movable side 29B and the fixed side 29A of the slide rail 29 do not become parallel when the movable shelf 3 is pulled out or pushed in, and the slide rail 29 is deformed. However, there is a danger that the bearing inside will jump out and be destroyed, and the movable shelf 3 will fall, but according to the present invention, the connecting members 30 and 31
Thus, the degree of balance is ensured, so that such an accident can be prevented.

In the above-described embodiment, the movable shelf 3 is located inside the bracket inner surface plate 28A of the bracket 28, but this is performed when obstacles such as fluorescent lamps are present on both sides of the opening 16 of the showcase 2. In order to avoid this, the movable shelf 3 can be pulled out. When such an obstacle does not exist, the bracket inner surface plate 28A is deleted as shown in FIG. It may be extended to the front of the shelf support 25. However, in the related art, such an expansion is impossible because the fixing tool 40 exists above the movable shelf 3. However, according to the present invention, the fixing tool 40 does not exist above the bracket 28 as in the related art, 3, so that the mounting area of the movable shelf 3 can be increased, and the shelf support 2 in the central portion can be extended.
In FIG. 5, the distance between the movable shelves 3 arranged side by side as shown in FIG. 8 can be reduced.

[0026]

As described in detail above, according to the first aspect of the present invention, the position of the bracket is determined between the engagement holes with which the plurality of claws are engaged.
Is fixed to the bracket while inserted in the engaging hole
Since the fixture is provided, it can effectively cope with the acting force applied to the bracket when the movable shelf is moved or pulled out, and the shelf device having the movable shelf by reliably preventing the shelf device from dropping. Safety can be improved. In particular, since the fixture is located between the upper and lower claws, it does not protrude up and down from the bracket, so that there is no interference with the movable shelf and other brackets, multi-stage by expanding the movable shelf and reducing the shelf interval Is easy.

According to the second aspect of the present invention, the balance of the brackets is ensured by the connecting members crossing each other and connected at the crossing portions, so that the rail is prevented from being broken by the operation of the movable shelf. In addition, the shelves can be prevented from falling off.
